tMapRDBLookupInput

Provides lookup data to the main flow of a streaming Job.

tMapRDBLookupInput extracts columns corresponding to schema definition. Then it passes the extracted data to the next component.

It passes on the extracted data to tMap in order to provide the lookup data to the main flow. It must be directly connected to a tMap component and requires this tMap to use Reload at each row or Reload at each row (cache) for the lookup flow.
